In a preferred configuration 3021 of cylindrical tube 3010, second tube-segment length L3 preferably comprises about 11 inches; this length produces a preferred overall apparatus length L1 of about 24 inches (when second tube segment 3034 is joined with first tube segment 3032).

In second preferred configuration 3023 of cylindrical tube 3010, second tube-segment length L3 preferably comprises about 22 inches; this longer preferred length produces a preferred overall apparatus length L1 of about 36 inches (when second tube segment 3034 is joined with first tube segment 3032). The 24-inch unit is preferably used with average-sized trees, while the 36-inch unit is preferably designed for palm trees and deeper rooted trees.

Second tube segment preferably comprises an inner diameter of about one inch and a uniform sidewall thickness of about 5/32 inch. First tube segment 3032 preferably comprises a proximal end 3038 having an inner diameter of about one inch and a sidewall thickness of about 5/32 inch, and a distal end 3040 having an outer diameter of about one inch and a sidewall thickness of about 5/32 inch. Preferably, cap 3008 can be fitted to either the proximal end 3038 of first tube segment 3032 or top end portion 3012 of second tube segment 3034.

The plurality of passages 3020 of cylindrical tube 3010 are preferably structured and arranged to disperse aqueous liquid 114 along substantially a full length L1 of modular plant waterer 3000 (extending between top end portion 3012 and bottom end portion 3014). First tube segment 3032 preferably comprises a regular pattern of apertures (passages 3020) preferably extending along first tube-segment length L2, as shown. Passages 3020 are preferably located on opposite sides of the first shaft, and preferably comprise a central column of larger holes (relative to the smaller holes), as shown. Preferably, each larger hole comprises a diameter of about 0.2 inches. Preferably, around each larger hole, in an X-like configuration, are preferably four smaller holes (relative to larger holes, as shown). Preferably, each smaller hole comprises a diameter of about 0.15 inches. Preferably, the center-to-center distance between large and small holes is about 0.6 inch. Passages 3020 of first tube segment 3032 preferably comprise an aggregate open area of at least about one quarter of one square inch. Such an arrangement provides regularly spaced holes to allow for a pattern of fluid dispersion out of the lower portion of the first shaft.

Passages 3020 of second tube segment 3034 preferably comprise a linear pattern extending along second tube-segment length L3, as shown. Each aperture (passage 3020) comprises a diameter of about ⅜ inch and an aperture to aperture spacing S of about four inches.

Periodically, as a shrub or tree grows and roots extend farther away from the trunk, repositioning of modular plant waterer 3000 to a location beneath the outer edge of the leaf canopy is recommended. The uppermost aperture 3042 within the sidewall 3016 of second tube segment 3034 preferably functions as a tool-receiving aperture structured and arrange to receive at least one hand-grippable tool. This tool-receiving aperture 3042 is preferably structured and arranged to assist user removal of cylindrical tube 3010, from soil 104, using such hand-grippable tool, such as, for example, a screwdriver. A user inserts a screwdriver or like tool through the apertures and pulls upward to release the apparatus from the soil. A Slight twisting of the tube assists removal. Aperture 3042 preferably remains without a covering of fabric 142, to permit passage of the tool through the tube. Applicant has found that rotation of cylindrical tube 3010 about every six months keeps small roots from entering through passages 3020.

FIG. 30 shows a side view, in partial section, illustrating the installation of modular plant waterer 3000, comprising alternate preferred configuration 3004, according to another preferred embodiment of plant watering system 100.
